help me please i was try to create javafx stacked bar on myproject. i'm so confused to create that bar, it's not common for me. i have read any ask question and any answer on stacked over flow but, my program still not showing up. this is my code.
package stackedbar;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.chart.CategoryAxis;
import javafx.scene.chart.NumberAxis;
import javafx.scene.chart.StackedBarChart;
import javafx.scene.chart.XYChart;
import javafx.scene.control.Label;
/**

public class FXMLDocumentController implements Initializable {
private Label label;
@FXML
private StackedBarChart<String, Number> chartBar;
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
start();
}
public void start() {
// TODO Auto-generated method stub
//Configuring xaxis and yaxis
CategoryAxis xaxis = new CategoryAxis();
NumberAxis yaxis = new NumberAxis(1000,300000,1000);
xaxis.setLabel("Months");
yaxis.setLabel("Number of users");
//Configuring StackedBarChart
StackedBarChart chartBar = new StackedBarChart(xaxis,yaxis);
chartBar.setTitle("Popularity of Programming languages");
//Configuring series for java
XYChart.Series java = new XYChart.Series<>();
java.setName("java");
java.getData().add(new XYChart.Data<>("Jan",10000));
java.getData().add(new XYChart.Data<>("Jan",130000));
java.getData().add(new XYChart.Data<>("Feb",50000));
java.getData().add(new XYChart.Data<>("Mar",60300));
java.getData().add(new XYChart.Data<>("Apr",105600));

java.getData().add(new XYChart.Data<>("Nov",102400));
java.getData().add(new XYChart.Data<>("Dec",200000));
//Adding series java to the stackedbarchart
chartBar.getData().add(java);
//Configuring series python
XYChart.Series python = new XYChart.Series<>();
python.setName("python");
python.getData().add(new XYChart.Data<>("Jan",50000));

//adding python series to the stackedbarchart
chartBar.getData().add(python);
}
}
create FXML with scene builder, code editor on netbeans Program just show like this enter image description here
Help me please
You're creating a new StackedBarChart
inside your start
method. You then configure that chart and never add it to the scene. However, you are already injecting a StackedBarChart
via FXML—you should be configuring that one. Remove the following line from start
:
StackedBarChart chartBar = new StackedBarChart(xaxis,yaxis);
